That's fantastic. So much great content was lost when the original sites went down

It wasn't lost per se, Geocities was archived and you can download a torrent: https://wiki.archiveteam.org/index.php/GeoCities

That page links to a web-accessible archive here: https://geocities.restorativland.org/

In fact there's some interesting 90s queer history here: https://geocities.restorativland.org/WestHollywood/Castro/
